Michel Blanc 1c22f2146e Adds configurable jinja2 extension loading
Jinja extensions adds features to the jinja2 templating engine. This
patch allows module loading for the templating engine vian an
ansible.cfg configuration key (jinja_extensions).
The default behaviour doesn't change (no module loading).
Requested modules can be added coma separated in ansible.cfg

Adds whitespace handling in jinja_extension config

Added whitespace handling in jinja_extension configuration directive, so
things stay safe if user adds spaces around comas in the directives
list.

Adds config example for jinja_extensions

Added config example with multiple extentions for jinja_extensions
